This new source of mechanical power began the Industrial Revolution, "one of the most profound social transformations in history" . Interestingly, James Watt felt that high-pressure steam was dangerous and discouraged the used of coal-powered steam engines for transportation.
Water was the main source of mechanical power, and by the end of the seventeenth century, England alone is thought to have had some 20,000 working mill. There was much debate on the relative efficiencies of different types of waterwheels.
A watermill or water mill is a mill that uses hydropower.It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering.Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may be comprise gristmills, sawmills, paper .

An outline of the history of mills in the British Isles, with bibliography and notes on unpublished sources and images. . More familiar today are the vertical wheel mills. In the undershot type the water turns flat blades from the bottom of the wheel. . Most villages had a mill to grind corn, but this power-source could be turned to other uses.
Hydraulic ram water pumps use downhill water pressure to pump water much higher than it started, with no other power needed. A 20ft fall is enough to push water 150 feet above the source or more. Or as little as a 2ft fall between the water source and the pump at a flow rate of 1 to 3 gallons per .
A History of the Water Wheel Water wheels and their development can be seen in three distinct types of water mills. The first and simplest type of water wheel, and probably the easiest to construct is the horizontal wheel used for driving a millstone through a vertical shaft attached directly to the wheel.

The most ancient water wheel was built with a vertical axle for transmit power to the millstone; although the vertical axle technology was the simplest, its efficiency was quite low. The first kind with horizontal axle was the undershot water wheel, already described by Vitruvius in 27 BC.
The kinetic energy of the flowing river turns the wheel and is converted into mechanical energy that runs the mill. In the late 19th century, hydropower became a source for generating electricity.

Neander97 / Historical Trivia: The mechanical principles underlying the working of a water-powered mill are, from the hindsight of the 20th century, quite simple. Whether undershot or overshot, the water propels the wheel, which transfers the water's power to the drive-shaft, which turns the millstones. Of course, waterwheels were employed to do more than mill grain, by the 10th century C.E .
